Answer:
It decreases by 21% in circulation.
Step-by-step explanation:
In order to find the percentage decrease, first, you have to find the difference of the circulation of a newsletter :
[tex]2600 - 2054 = 546[/tex]
Then, you have to divide by the original amount and multiply by 100 :
[tex] \frac{546}{2600} \times 100[/tex]
[tex] = \frac{21}{100} \times 100[/tex]
[tex] = 21\%[/tex]
